Internal Or external Wastegate

[sherwood87]

Which is better for a t3/t4 50 trim setup for a 94tsi.. A wastegate thats on the manifold or one thats between turbo and 0o2 housing?

Do a search... much info available already. External = more accurate and responsive, internal = lower cost. It really depends on your application.

there both about the same(external wastegate), it probally be easier and cheeper to get an 02 housing that has is wastegate ready, as opposed to buying a manifold that is 02 ready, or having a machine shop press a mount onto your manifold. internal is defintaly worse than external,in a '' boost control'' sense. external is more accurate when dealing with higher boost levels,but also is a little more costly and a little more work to get goin. in my opinion i would go external
mounted on the o2
